APPARATUS FQRMAKINGVB AGS on CONTAINERS.

Be it known that I, IVILLIAM Rose, a subject cf the Kingof GreatBritain, residing at Albion WVorks, Gainsborough, England,

have invented new and useful Improvements in or Relating to Apparatusfor ';Making Bags or Containeisof which the following is aspecification. i i V This invention relates to apparatus for makingbags, or containers, the said appa ratus being of the kind in whichmandrels, or formersfl (hereinafter; referred to as formers) areemployed upon whichthe bags, orcontainers, are made, the said bags,

or ccntainers, being afterward delivere'djto a. series of devices, suchfor instance, as weighing, or measurmg'and. filling, devices, orto anumber of operators who weigh, or

measure and fill, or Ictherwise deal with the v series of bags, orcontainers, can be stamped,

or embossed, or otherwise marked, with a distinctive marking todistinguish vit from the bags, or containers, of another seriesso that,after the said bags, or containers, have been fed, or supplied, to anumber of operators, or to a series of-measuring, orweigh ing, orfilling devices, or thelike, and have i been dealt with thereby,.it can,at any time, be ascertained by which operator, or by which of a seriesofmeasuring, or weighing, or filling, devices, or the like, anyparticular bag, or container, was dealt with,

According to this invention I employ a suitable number of distinguishingmarks, or characters, which may be carried by suitable levers, or bars,operated by any suitable mechanism so as to cause the said marks, orcharacters, to mark thepaper, cardboard, or other material, of which thebags, or containers, are made, while the said bags, or

containers, are on the former.. -I prefer to' use a number ofdistinguishing marks, or characters, recurring in consecutive order,

and it is also preferred-that the number of different marks, orcharacters, shall corre; spond to the number of operators, or measuring,weighing, 0r filling. devices employed. For example, presumingtheapparatus tobe I Specification of Letters latenti Application fildMay 5, 1914:. Serial IND. 836,508.

of the intermittent rotary kind and 150 vided' with eight formers and 7that four operators are employed for charging the sa1d bags, or contaners, two sets, or series,

of distinguishing marks, or characters, can

beiemployed for instance, two sets of the letters A; B. C. and, D, sothat the bags, or,

containers, made on-the first and fifth formers. will be, marked withthe letter A,

those made on the second and sixth formers willbe marked with the letter,B,

thosel made on the third and seventh formers will be marked with theletter C and those made on the fourth andeighth formers will be markedwith the letter D'.

The marked bags or containers are then delivered, by any suitable means,'(such for example as a travelingbelt, or. traveling belts) to the four0perators, the bags, or containers, marked A passing to the firstoperator, thosemarked B passing to the second operator, those marked Cto the third operator, and thosev marked D to the fourth I operator. Inthe apparatus wherein a lever,or bar, is employed to press upon thelongitudinal seams of the bags, or containers, while on the formers, thesaid mark, or marks,;or character, or characters, is, or are, preferablycarried by the said levers, or bars,QorI may employ other suitablelevers, or -.pressers, toapply the said 1 mark, or character,.or marks,or characters,

to the said bags, or"containers, in any desired position,

Instead of employinglettersas identifi cation marks'I may employnumerals, a

number of dots, or dashes, or any other sufficiently distinctive marks,or characters.

Theacccmpanying drawings illustratethe preferred means for-carrying thisinvention into practical efi'ect,,Figures 1, 2, and 3 showing in viewsat right angles to each other so much of an apparatus for making bags,or containers, as is necessary to show the application of this inventionthereto; Fig. s r-is a detail showing the -indicating means in itsoperative position; Figs. 5, 6 and 7 show, in views at right angles toeach other, the indicating meansseparate from.

theapparatus and Fig. 8 shows, in perspecpacket with marks tive, acompletely folded of identification thereon Referring to Figs. 1, 2and?) the apparatus for making the bags, or containers, is shown ascomprising an intermittently rotating vertical shaft 1 having mounted atO thereon a number of formers of which only one (marked 2) is shown inthe said figures, eachbeing provided with a presserfoot, or bar 3, andmeans for operating it whereby the said resser-foot, or bar, is

caused at the proper times, to descend and oted at 4, to a stationarybracket 5 one arm.

6 of which lever is actuated through an antifriction roller 7, by a cam8, on a rotating shaft 9. The larger part of the cam 8 acts to depressthe arm 6 of the said bell-crank lever which causes its other arm 10 tobe moved free of an upwardly projecting arm 11 on the presser-foot, orbar, 8, and the smaller part of the said cam permits the arm 6, to beraised by the action of a spring 12, so that the said arm 10 is broughtinto engagement, through an anti-friction roller 13, with the projectingarm 11 on the presser-foot, or bar, 3 and turns the said presser-foot,or bar, on its pivot 14 in opposition to the action of a spring 15.

The means for marking the bags, or containers, in the example shown inthe accoman in drawin s consists of a ro'ection .or projections, 16,formed on the underside of a piece 17 hinged to the presser-foot, orbar, 3 which projections enter a groove, or recesses, 18, formed in theupper side of the former 2, Four projections 16 are shown in Figs. 1, 4,5, and 6 but the number of such projections will be varied according torequirements, for instance, in the example of apparatus before referredto having, it is presumed, eight formers and the bags, or containers,made thereon delivered to four operators, the first and fifth formerswill each be provided with but one projection, the second and sixthformer will each be provided with two projections, the third and seventhformer will each be provided with three projections and the fourth andeighth formers will each be provided with four projections. Thepresser-foot, or bar, 3 is held, by the arm 10 of the bell-crank lever,in its raised position while the material of which the bag, orcontainer, is made is folded around the longitudinal sides of the former2, the said bellcrank lever then releases the said presserfoot, or bar,which, by the action of the spring 15, then descends and causes the prothereon would be identified by the absence of any mark, or character;and again, instead of the marks, or characters, being carried by thePresser-foot, or bar, or other lever, they may be carried by the formersand the grooves or recesses, be formed in the said Presser-foot, or bar,or other lever. Bag, or container making apparatus provided with meansfor marking the said bags, or containers with a series of identificationmarks, or characters, as hereinbefore described and for delivering thebags, or containers, having the same identification marks, orcharacters, to the same operator, or to the same measuring, filling, orweighing, or other device, identified with such marks orcharacters,provides ready means of ascertaining whether, or not, any opera tor, orany measuring, filling, weighing, or other device, has been performinghis, or her, orits, duty satisfactorily.

What I claim is 1. In apparatus of the character described, a series ofintermittently actuated formers adapted to act each'upon a separatecontainer, and a series of different identification marking devices onefor each former, and serving to mark the container operated upon therebywith its peculiar mark, for the purpose described.

2. In apparatus of the character described, a series of formers adaptedto act each upon a separate container, a common support for said formersadapted to bring each former successively into operating position, meansto actuate the formers when in operating position, and an independentmarking device for each former whereby the containers from eachformerbear an identification mark peculiar to said former.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM ROSE.
